Two jailed for conspiring with NUS lab executive to cheat more than S$350,000. I've heard from experimental colleagues that equipment purchasing system at NUS is very slow and inefficient. Now I understand!
Our short review on physics applications of topological data analysis is now out at arXiv:2206.15075. I hope it provides a good overview of the recent literature on this subject. I certainly learned a lot writing it!
Another probably controversial preprint was posted a few weeks ago: Observation of strong backscattering in valley-Hall topological interface modes. From the abstract: "We find no improvement in the propagation losses relative to
topologically trivial waveguide modes with the same group index, even for
state-of-the-art silicon photonics...our work raises fundamental questions about the existence
of topological protection against real-world disorder in
time-reversal-symmetric photonics." This is a must-read for anyone working on topological photonic crystals.
At CQT we will have our first in-person colloquium in more than two years (!) on 14th July, given by Prof. Michael Tobar: Precision Metrology with Photons, Phonons and Spins: Answering Major Unsolved Problems in Physics and Advancing Translational Science.
